Application January 11, 1939, Serial No. 250,363

16 Claims.

This invention relates to shoes in which the outersole is secured by permanent cement, and is illustrated in this application as embodied in a shoe of this description having an interlock between the outersole and the lasted shoe of the general type shown in my Patent No. 2,065,786, granted December 29, 1936, though in its broader aspects it is not limited to shoes of this particular type.

One object of this invention is to provide a construction whereby removal of a worn sole and the attachment of a new one is facilitated. To this end a line of stitching for securing the tread portion of the sole is provided, together with a construction whereby this line of stitching may be easily severed in a manner to free the tread portion of the sole from the shoe.

For a more complete understanding of this invention, reference may be had to the accompanying drawing in which Figure 1 is a perspective view of an outersole having a rand portion partly severed therefrom by a pair of channels.

Figures 2 and 3 are detail sections through the marginal forward portion of the shoe showing successive operations and employing the shoe sole of Figure l.

Figure 4 is a View similar to Figure 3, but showing the stitches out and the rand fully severed preparatory to a re-soling operation.

Figure 5 is a view similar to Figure 2, but showing a modification.

Referring first to Figures 1 and 2, l indicates an outersole which is channeled inwardly from its outer edge along the line 2 throughout at least the shank and forepart portion. It is also channeled downwardly and outwardly from its top face from a position inwardly of the outer margin as at 3, toward the inner end of the edge channel 2, thus to define between these channels what might be termed a rand 4, only partly severed from the top face of the outersole, being united with the outersole by the integral neck portion 5 between the channels 2 and 3 and with its top face lying flush with the adjacent face of the outersole. For a spring heel shoe the channeling would go entirely around the shoe. The top face of this rand is secured by a permanent cement to a lasted shoe.

As shown in Figure 2, this lasted shoe coinprises an innersole i6 overlaid with a reinforcing fabric H and provided with a lip [2 about the margin thereof. Against the outer edge of this innersole l6 and to the outer face of the lip 12 is lasted and secured the upper materi als, herein shown as comprising an outer layer I4 and a lining [5. As shown the upper materials are secured to the innersole as by a line of stitching it, though for the purpose of this invention, it might be secured in any other desired manner. The parts thus secured together and trimmed present a marginal tapered flange I! having a substantially fiat lower face 13 in substantial continuation of the lower face of the fabric reinforcement H. The top face of the rand strip 4, suitably roughened, if necessary, is then cemented by permanent cement to the lower face of the reinforcing fabric II and to the face l8 formed by the trimmed edges of the rib l2 and of the upper materials, and then, preferably, to provide an interlocking engagement between the lasted shoe and the sole, a welt strip 26 (Figure 3) having a beveled face 2| mating the face I! of the lasted shoe, is secured in position against this face and against the exposed stitching [6 as by permanent cement, and the strip 26 is also secured to the rand and the lower or tread portion of the sole as by the outersole stitching 22. It will be noted that this outersole stitching is placed outwardly of the shoe upper above the sole similarly to the usual outersole stitching of a welt shoe, and extends through the rand 4 outwardly of its integral securing portion 5 and through the marginal portion of the tread member of the outersole which presents the tread face 25. Thus the stitching 22 passes across the cut formed by the channeling operation for the outer channel 2. It may or may not, as desired, engage the margins of the upper materials.

When it is desired to remove the outersole, as for resoling, it is then only necessary for the repairman to insert a knife in the outer channel 2 to sever the stitching and also sever the integral connecting portion 5 between the tread portion of the outersole and the rand. Since the rand only is permanently cemented to the lasted shoe, this rand is then freed from the tread portion of the outersole as shown in Figure 4, there being no cement, or, if cemented, only a temporary cement between the outersole and the lower face of the innersole. By thus severing the stitches 22 and completing the severance of the rand strip, the tread portion of the outersole is freed to be removed from the shoe and a new sole corresponding to the worn tread portion returned in position and secured as by a line of outersole stitching such as the stitching 22 shown in Figure 3. The new outersole tread member is thus attached only by stitches which can be severed when this new sole has been Worn to such an extent that renewal of the tread portion of the shoe is again advisable. Or, if desired, the repair sole may be permanently cemented to the rand.

In some cases it may be desired to waterproof a leather outersole tread portion, but difficulty may be experienced, where this is done, in obtaining a cement bond between the waterproofed tread member and the remainder of the shoe. In order to overcome this difiiculty and yet retain the advantages of repair possessed by the structure shown in Figures 1 to 3, a modification may be employed as illustrated in Figures 4 and 5. This modification may consist in completely severing the rand from the top face of the outersole member instead of leaving the rand with an integral attachment to the tread portion of the outersole, the outersole member thus being recessed on its top face about its margin complemental to the rand whereupon the tread portion may be made water-resistant or waterproof. Since the rand and the remainder of the outersole were originally the same piece of material, they fit together accurately when re-assembled and in the finishing operations the texture is so similar that the two blend together very nicely, The rand is then returned to its former position, and for ease of handling is preferably temporarily secured as by a temporary cement to the top face of the outersole. No very strong adhesion of these parts is necessary, it being only necessary to provide for sufiicient adhesion to avoid possibility of displacement on the tread member until after the outersole stitching has been effected, whereupon there is no more need for the temporary securement. This is illustrated in Figure 5, where the rand strip is shown as entirely severed from the tread portion 4!. This tread portion 4| is then treated with a waterproofing compound and the rand either first returned to its position thereon, or, if desired, it may be first cemented to the lower face of the lasted shoe. Where it is first temporarily cemented to the tread portion, this tread portion holds the rand in proper condition to be thereafter cemented by permanent cement to the lasted shoe, so that no form to hold the opposite sides of the rand strip in proper position is necessary in order to insure correct positioning of the rand. Whichever method is adopted, however, the rand strip is secured to the bottom of the lasted shoe by a permanent cement and if initia ly secured at all to the tread portion, it is. secured only by a temporary cement.

After the parts have been thus assembled, a welt strip 29 such as shown in Figure 3 placed over the outwardly and downwardly tapered marginal portion of the lasted shoe, is preferably secured by permanent cement to the lasted shoe flange H, the parts being secured together as by stitching with outersole stitching 22, as shown in Figure 3. To renew this sole 2!, it is now only necessary to insert a knife between the outer edges of the outersole tread portion 4! and the rand 49 and sever the outersole stitching. whereupon the tread portion ll may be removed and a new one substituted, it being evident that at this time the rand A!) is permanently cemented to the lasted shoe and need not be disturbed.

From the foregoing description of certain embodiments of this invention, it should be evident to those skilled in the art that various changes and modifications might be made therein without departing from the spirit or scope of this invention.
